Definitions

  • This invention relates to a method of fabrication of parts of three-dimensional fabrics.
  • three-dimensional fabrics are constituted by threads, fibers, slivers and so forth, these latter being oriented within the fabric in three different directions which are usually at right angles to each other.
  • these fabrics find many applications, especially when they are formed of threads or of high-performance fibers such as fibers of carbon, graphite or similar materials.
  • these fabrics are advantageously employed in the manufacture of re-entry units of rockets or missiles as well as in the construction of thermal shields and brake linings.
  • Some methods entail the use of assemblies or machines which serve to separate layers of parallel threads so that the threads which form the second and third directions can be inserted in succession.
  • Other methods consist first in forming a bidirectional structure by successively stacking either layers of flat fabrics with crossed warp and weft threads or layers of parallel threads oriented alternately from one layer to the next in two directions, then in inserting the thread of the third direction by means of a method of sewing in a perpendicular or oblique direction with respect to the plane of the layers.
  • the present invention is directed to a method of manufacture of parts of three-dimensional fabrics for obtaining parts having precise shapes and dimensions as well as good rigidity by means of a method of sewing, starting from a structure of bidimensional type.
  • the method in accordance with the invention consists in successively stacking layers of bidimensional fabrics or layers of parallel threads extending alternately from one layer to the next in a first direction and a second direction, then in sewing the stack thus formed in parallel lines by means of a thread which extends in a third direction.
  • the method is distinguished by the fact that said layers are stacked on a support of pyrolyzable material, that the stack of said layers and said support are sewn by means of the thread which extends in the third direction and that the assembly thus obtained is subjected to a temperature within the range of 800° C to 1200° C in the presence of a stream of gaseous hydrocarbon in order to pyrolyze the material which constitutes said support and in order to deposit pyrolytic carbon on the threads which form said three-dimensional fabric.
  • a suitable pyrolyzable material When selecting a suitable pyrolyzable material, it is necessary to take into account the fact that on the one hand the support must have a certain degree of rigidity without thereby offering excessive resistance to the passage of a needle and on the other hand the fact that it must be capable of pyrolyzing within a temperature range which is compatible with the possibilities of pyrolytic graphite or carbon deposits from a gaseous hydrocarbon.
  • Use is advantageously made of paperboard or balsa wood which undergo complete pyrolysis at a temperature below 1000° C.
  • the heat treatment is carried out in the presence of a gaseous hydrocarbon which is selected from the group comprising methane and propane.
  • sewing of the stack of layers and of the support is effected by the thread which extends in the third direction with a lockstitch formed by means of an auxiliary shuttle thread.
  • the tension of the two threads is adjusted so as to ensure that the knot between the two threads is formed within the thickness of the support.
  • the auxiliary shuttle thread is advantageously formed of pyrolyzable material such as cotton or rayon, for example.
  • the support comprises a graphite core surrounded by pyrolyzable material and said graphite core is extracted after the assembly has been subjected to the temperature which is necessary for pyrolyzing said material.
  • FIG. 1 illustrates the first step of the method, namely the sewing of the stack of layers and of the support
  • FIG. 2 illustrates the second step of the method, namely the heat treatment of the assembly which is thus obtained
  • FIG. 3 illustrates the second step of the method in accordance with an alternative embodiment of the invention which relates to the support structure.
  • the method in accordance with the invention can be applied to the construction of parts having different shapes and any desired profile such as, for example, parts of cylindrical shape, of frusto-conical shape, of parallelepipedal shape or parts in the form of plates or discs.
  • FIG. 1 there is shown the support 1 of balsa wood of cylindrical shape which corresponds to the dimensions of the part to be constructed.
  • a number of superposed layers 3 of carbon fabrics or carbon threads which may or may not be twisted have been placed beforehand on the external surface of said support 1 so as to constitute a bidimensional structure of desired thickness around the cylindrical support 1.
  • the cylindrical support 1 covered with the stack of layers 3 is placed on a sewing machine (not shown in the drawings) which is suitably adapted to this application.
  • Said sewing machine has a sewing head fitted with a needle 5 through which is passed the carbon thread 7, said thread being intended to be inserted in the third direction.
  • the sewing head is also fitted with another needle 9 which serves to pierce the entire stack prior to insertion of the needle 5 which carries the carbon thread 7 in order to facilitate the introduction of said needle 5 through the stack of layers 3 and the support 1.
  • the sewing machine is equipped with a shuttle (not shown) on which is wound a fairly strong auxiliary thread 11 such as a cotton or rayon thread and the cylindrical support 1 is mounted on the sewing machine in such a manner as to ensure that the needle 5 is capable of passing through its surface at right angles to the layers 3 and that the shuttle is located on the other side of this surface, namely within the interior of the cylindrical support 1.
  • the sewing machine is capable of operating so as to form a lockstitch by means of the stitching thread 7 and the shuttle thread 11.
  • a first sewing line 13a is formed along a generating-line of the cylindrical support 1.
  • the tension of the stitching thread 7 and the tension of the shuttle thread 11 are adjusted beforehand so as to ensure that the knot between the two threads is located within the thickness of the cylindrical support 1 as close as possible to the internal surface of said support.
  • the portion A illustrates in vertical cross-section the structure of the assembly which is obtained after the sewing operation and shows the stack of layers 3 which are sewn together by means of the carbon thread 7 which is passed through said stack from one side to the other in a direction substantially at right angles to the plane of the layers 3 in the form of a continuous thread in tension, the visible portions of which are located on each side of the end faces of the stack of layers 3.
  • the shuttle thread 11 which is employed for the purpose of forming the lockstitch in turn forms through the cylindrical support 1 a continuous thread disposed in a curve of sinusoidal shape and small amplitude, one of the summits of which is located substantially on the internal surface of the cylindrical support 1 whilst the other summit is located within the interior of said support and as close as possible to its internal surface.
  • the assembly thus obtained is then placed in a furnace 20 which is illustrated very diagrammatically.
  • the furnace 20 is heated to a temperature of 1000° C and a gaseous hydrocarbon such as methane is introduced continuously into the furnace enclosure.
  • the balsa wood which constitutes the support disappears as a result of pyrolysis and decomposes into volatile products whilst the methane is dissociated and produces carbon or pyrolytic graphite which is deposited on the solid surfaces within the furnace 20 and especially on the threads of the three-dimensional structure which is accordingly endowed with rigidity.
  • the shuttle thread is also pyrolyzed under the action of said temperature and there is obtained at the end of the operation a part having the shape of a cylindrical ring as shown in the portion B of said figure, comprising the stack of layers 3 through which the carbon thread 7 is passed. Said part has an internal diameter which is substantially equal to the external diameter of the cylindrical support 1 and has a thickness substantially equal to that of the stack of layers 3 which have previously been placed on said support.
  • the cylindrical support 1 illustrated in the portion A of this figure comprises a graphite core 1a surrounded by pyrolyzable material 1b such as balsa wood.
  • the operation which consists in sewing the superposed layers on the cylindrical support 1 is carried out in exactly the same manner and the assembly thus obtained is then placed within the furnace 20 which is heated to a temperature of 1000° C in the presence of a stream of methane.
  • the pyrolyzable material 1b disappears and dissociates into volatile products.
  • the pyrolyzable material 1b disappears and dissociates into volatile products.
  • the threads which are intended to form the three-dimensional fabric can be either of the same type or of a different type. It is possible in particular to employ graphite threads, glass threads and silica threads which may or may not be in the form of twisted yarn.
